First published in Galaxy, May 1953.

Though the original story is still under copyright in the United States the X Minus One adaptation (above) and the original Don Sibley illustrations, from Galaxy, May 1953, (below) are in the PUBLIC DOMAIN.

This is a truly terrible story, by someone who is normally perceived to be a great author, Robert Bloch. I suspect Bloch chose the pseudonym for this one because it is so bad. Indeed, I suspect this is precisely the kind of story Isaac Asimov was trying to defeat with his Three Laws of Robotics. But beyond the dangerous robot trope it also features, at least to my ears, the most creepily lascivious robot ever!

Junior is oily, immoral, and oversexed.

Ewww!

UPDATE:
Here’s Robert Bloch’s introductory essay to Almost Human (as written for My Best Science Fiction Story a 1949 anthology edited by Leo Margulies and Oscar J. Friend):

I bet most folks think that the closest Robert A. Heinlein came to tackling the topic of religion was Stranger In A Strange Land. But I think that novel has got too much other stuff going on in it. To get a better idea, check out his terrific 1941 short story Universe (later combined with another short story for the fix-up novel entitled Orphans Of The Sky).

The people of Universe live under an oppressive theocracy, with the death penalty given for heretical ideas. In the script for the radio dramatizations one character describes it as a society of “regimented slaves.”

Universe offers many, many sparky ideas – all of which are centered around religion and cosmology.

When asked about heaven the main character says this:

“The peasants believe [in] it literally but many of the younger scientists, like myself, know that it is figurative, symbolic.”

Turns that he’s wrong, that the foundations of his religion are based in a real history, that his god was once alive, and that the belief he scoffs at (and others kill in the name of), are based facts about their universe. It’s absolutely thought provoking soft sf bounded by a hard SF that only someone like Robert A. Heinlein could pull off.

And, unlike the original short story, which is rather hopeful, the end of the radio dramatization is deeply noir.

Here’s an adaptation of a science filled Science Fiction story (about climate change) that I’ve posted about previously – I’m quite fond of it. Check out the wonderful original magazine illustrations to go with it!
